Message Examples

An example of a regular information-level parse error (cannot find a required field) is:

at 0: com.stc.swift.runtime.SwiftUnmarshalException: mt_103.Mt_103: 0:
 Failed to parse required child(Data).

An example of a parse error with the debug level enabled (cannot find a required field) is:

at 146: null: com.stc.swift.runtime.SwiftUnmarshalException:
 mt_543.Mt_543.Data.GeneralInformation.FunctionOfTheMessage: 146:
 Failed to parse required child(String2).

Given this path to the data, you can determine where in the message the parser failed by looking at:

• The SWIFT User Handbook

• Structure of the OTD in the Enterprise Designer’s OTD Editor

• Javadoc for the OTD

See MFVR Errors for MFVR-specific error information. For more detailed error information, see Error Message Information.

Parse Debug Level Message Example

The following example shows error message output at the parse debug level:

[main] PARSE - Swift: matchDelimSkip("{1:") --> true.
[main] PARSE - Swift: getData("F|A|L") --> "F".
[main] DEBUG - Swift: mt_502.Mt_502.BasicHeader.AppIdentifier: 3: Mapped data("F").
[main] DEBUG - Swift: mt_502.Mt_502.BasicHeader.AppIdentifier: 3: Mapped rep[0].
[main] PARSE - Swift: getData(charSet, 2, 2) --> "01".
[main] DEBUG - Swift: mt_502.Mt_502.BasicHeader.ServiceIdentifier: 4:
 The following is the last field successfully parsed the 4th 22a:
[main] PARSE - Swift: matchDelimSkip("22H::") --> true.
[main] PARSE - Swift: getData(charSet, 4, 4) --> "PAYM".
[main] DEBUG - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorH.String3:
 218: Mapped data("PAYM").
[main] PARSE - Swift: matchDelimSkip("//") --> true.
[main] DEBUG - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorH.String3:
 218: Mapped rep[0].
[main] PARSE - Swift: getData(charSet, 4, 4) --> "APMT".
[main] DEBUG - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorH.String5:
 224: Mapped data("APMT").
[main] DEBUG - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorH.String5:
 224: Mapped rep[0].
[main] PARSE - Swift: matchDelimSkip("
:") --> true.
[main] DEBUG - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorH: 213:
 Mapped rep[0].

The message goes on for several more lines, not indicating any error. Then the parser is looking for any more 22a’s, F or H, and does not find one. See the following example:

[main] DEBUG - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator[3]: 159: Mapped rep[3].
[main] PARSE - Swift: matchDelimSkip("22F::") --> false.
[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorF: 231:
 Failed to find BeginDelimiter("22F::").
[main] PARSE - Swift: matchDelimSkip("22H::") --> false.
[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails.Indicator.IndicatorH: 231:
 Failed to find BeginDelimiter("22H::").

The parser then looks for a 98a either option A|B|C as follows:

[main] PARSE - Swift: matchDelimSkip("98A::") --> false.
[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails.DateTime[0].DateTimeA: 231:
 Failed to find BeginDelimiter("98A::").
[main] PARSE - Swift: matchDelimSkip("98B::") --> false.
[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails.DateTime[0].DateTimeB: 231:
 Failed to find BeginDelimiter("98B::").
[main] PARSE - Swift: matchDelimSkip("98C::") --> false.
[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails.DateTime[0].DateTimeC: 231:
 Failed to find BeginDelimiter("98C::").

The parser finds no repetitions, which does not fit in the required range of 1 to 3 as described in the following example, so at this point, the parser fails, because no expected repetitions were found:

[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails: 231:
 Failed to match minimum repititions[ 1 < 0 <= 3 ].

[main] PARSE - Swift: mt_502.Mt_502.Data.OrderDetails:
145: Failed to parse
 required child(DateTime).
[main] PARSE - Swift: mt_502.Mt_502.Data:
145: Failed to match minimum
 repititions[ 1 < 0 <= 1 ].
[main] PARSE - Swift: mt_502.Mt_502.Data:
73: Failed to parse required
 child(OrderDetails).
[main] PARSE - Swift: mt_502.Mt_502: 
67: Failed to match minimum repititions[ 1 < 0 <= 1 ].
[main] PARSE - Swift: mt_502.Mt_502: 
0: Failed to parse required child(Data).
 [main] LAST  - Swift: Last match: mt_502.Mt_502.
